Galena boosts Abra production and mine life forecast
Jul 22, 2019· Galena Mining has delivered a feasibility study (FS) for the Abra base metals project in Western Australia that improves most key metrics compared to its prefeasibility study (PFS). The company has extended Abra's mine life from 14 to 16 years, annually producing highgrade leadsilver concentrate of 95,000 tonnes (up from 91,000) of lead and 805,000 ounces (up from 760,000 ounces) .

PbO is produced on a large scale as an intermediate in the conversion of lead ores, mainly galena into metallic lead. Commercial lead oxides can all be prepared by wet chemical methods. With the exception of lead dioxide, lead oxides are produced by thermal processes in which lead is directly oxidized with air.

Galena, a principal ore of lead, often bears silver, interest in which helped initiate widespread extraction and use of lead in ancient Rome. Lead production declined after the fall of Rome and did not reach comparable levels until the Industrial Revolution. In 2014, annual global production of lead was about ten million tonnes, over half of which was from recycling. Lead's high density, low melting point, ductility, .

Elevated levels of lead contamination in dust, air, and soil have been found around areas of mining activity. Mining waste in these areas has sometimes been used for driveways, fill material, and even in children's play areas. They have also migrated by natural process to yards, recreational areas, etc. See a map of historic mining.

Thus, when Peter Lorimier built a Scotch hearth in 1834 near Dubuque, Iowa, this new technology greatly lowered production costs and improved productivity within the lead industry. The frontier lead region from Galena into southern Wisconsin and Dubuque developed rapidly, so that by 1845 the district had a population of nearly 10,000 people and ...

By 1845 Galena was producing nearly 27,000 tons of lead ore and Jo Daviess County was producing 80 percent of the lead in the United States. Wisconsin lead mining peaked in the 1840s. In 1844, a third of the region's residents left for copper and iron mines elsewhere and the discovery of gold in California caused many others to head west in 1849.

Lead is produced from galena (PbS), and less commonly, cerussite (PbCO 3) and anglesite (pbSO 4). Commercial ores contain 4 to 12 percent lead. Galena often contains silver/gold and is associated with sphalerite (ZnS), pyrite (FeS 2), and chalcopyrite (CuFeS 2). Thus, byproduct and coproduct recovery are frequently important aspects of lead production.

Lead scrap has represented a portion of lead supply in the United States since the 1800's. The earliest known report of consumption of lead scrap was between 1867 and 1889, when a total of about 11,000 metric tons (t) of lead scrap were imported for unspecified uses in the United States (Kirchhoff, 1894).

Lead | Minerals Education Coalition
Lead. Lead (element #82, symbol Pb) is a very soft, bluegray, metallic element. It is primarily produced from the mineral galena. It has been used since antiquity. Water pipes in ancient Rome, some of which still carry water, were made of lead.
A Brief History of Lead Properties, Uses and Characteristics
Galena contains lead sulfide (PbS), as well as zinc and silver, all of which can be extracted and refined to produce pure metals. Other ores that are mined for lead include anglesite and cerussite. Other ores that are mined for lead include anglesite and cerussite.
Galena DNR
Galena is the principal lead ore mineral. It is lead sulfide (PbS). When pure, it contains percent lead and percent sulfur. Galena is bluishgray with a bright metallic luster when freshly broken, and dull gray when weathered. It is soft, brittle, and very heavy (about times as heavy as water).

The smelting process is essentially very simple. Pellets of Galena are heated until they reach melting point. Because lead has a low melting point any impurities are not melted and are left as waste. The molten lead can be allowed to drain from the fire hearth into a collecting pot and then poured into moulds to form blocks of pure lead metal.
